234 26th Ave, San Francisco, CA 94121

The two-story, three-unit multi-family residential building at 234 26th Avenue was constructed in 1974 and is currently owned by the Jackson Yu Living Trust. The property has undergone several significant improvements over the years, including a comprehensive window and patio door replacement project in 2017 ($28,000), which installed 32 new windows and 2 patio doors with energy-efficient specifications. Earlier renovations included a deck repair and replacement project for the second and third levels in 2003 ($10,000), and historical records show roofing work was performed in 1997.

The building has experienced multiple inspections and some compliance issues over its history. Notably, there was a recurring pattern of illegal unit concerns between 1998 and 2000, with the most recent inspection in 2003 documenting unauthorized apartments. A security violation regarding self-closing doors was noted and resolved in 2008.

More recently, the property faced significant infrastructure challenges, with seven documented sewage backup incidents in late 2021 (September to December) involving a 4-inch sewer vent line. Planning records indicate an ongoing effort to address parking and unit legalization issues, with an off-street parking variance approved to legalize a fourth unit. The building's most recent maintenance history shows attention to both exterior improvements and necessary repairs, though the age of some systems suggests continued monitoring of infrastructure performance may be warranted.
